We are also having this issue with signing on with our school domain
“Sorry, it looks like we’re having some internal issues.
Our team has been notified.”
It then allows me to attempt sign in with my Google account, which then returns the error:
“It looks like you’re having trouble signing in. Make sure you’ve enabled pop-up windows for SketchUp, then complete sign in using the pop-up window that appears.”
Could you also add our school G Suite domain to your registry please -
